As you all know my Old Boy Ash is in the later stages of renal failure, however lately he has just started pulling his fur out, was a big pile there last night and we just saw him doing it again a few moments ago, has anyone any ideas as to why he is doing this, is it a dementia type thing? or stress related, he does not appear to be stressed though, and Ash has always been a very laid back kitty, nothing worries him too much.

Any clues? your input appreciated , thanks.
